Coastal Commission Coordination

The California Coastal Commission is the ultimate permit authority in the Coastal Zone of San Luis Obispo County. In other words, the County can issue development permits in the Coastal Zone, but the Coastal Commission has the ultimate say in how the County's Local Coastal Program (Title 23) is interpreted. Strong coordination between Department of Planning & Building staff and Coastal Commission staff ultimately benefits applicants, as they often need to obtain initial permit authority ("retained jurisdiction") from the Coastal Commission as part of the development permit process.

Environmental Review
